l REGULATOR FOR MOTORS.

SPECIFICATION forming part of Letters Patent No. 268,641, dated December 5, 1882. Application filed August 16, 1882. (No model.) Patented in Germany December 9, 1880, No. 14,013.

To all whom at may concern:

Be it known that we, OSKAR DITTMAR and CARL SCHMIDT, subjects of the Emperor of Germany, residing at Vienna, Austria, and at Bockenheim, near Franktort-onthe-Main, Germany, have invented certain new and useful Improvements in Regulators for Motors; and we do hereby declare the following to be a full, clear, and exact description of the inven- [0 tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of our invention is to provide a new and improved governor or regulator for motors or devices for regulating the speed of motors.

The invention consists in a closed drum divided into compartments by radial partitions provided with slots or apertures which establish a communication between the compartments.

The drum is partly filled with a liquid, or sand, 2 5 or other granulated or pulverized material,

which is raised when the drum is rotated, thereby checking the speed; but the said liquid or other matter flows back through the apertures, and this prevents the speed from beingchecked too much. By varying the size of the drum and the sizes of the slots or apertures, so that the liquid or other material can flow back more or less rapidly, the speed will be checked more or less. The device can be adj ustedas desired. Reference is to be had to the accompanying drawings, forming partof this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of our improved regu- 4o lator for motors, parts being broken out and others shown in section. Fig. 2 is aplan view of the same, parts being broken out and others shown in section on the line a: m, Fig. 1. Fig. 3 is a side view of a modification of our im- 4 5 proved regulator for motors, parts being broken out and others shown in section. Fig. 4. is a cross-sectional plan view of the same on the line 0 P, Fig. 3.

Referring to Figs. 1 and 2, a hermeticallyclosed drum,A, is mounted on a shaft, D, and

the said drum is divided into a series of compartments, a, of equal size by radial partitions, E, which extend to within a short distance from the shaft B, whereby the compartments will be connected at their inner ends by an annular space, 0, formed around the shaft. An aperture, 1), is provided in each partition E near the outer ends, so that the compartments Will also be placed in communication with each other by the said apertures. A fluid, sand, or other granular or pulverized matter is placed into the drum to fill about one-third of the same, as shown. If the shaft D is at rest the liquid in the several compartments will have the same level; but if the shaft 1) is rotated 6 the liquid in the compartments raised toward the shaft in the direction of rotation will be higher than the level of the liquids in the other compartments, and will have the tendency to turn the drum and shaft in the inverse direction of the arrow, and will thus retard or check the movement of rotation of the shaft. The liquid immediately flows toward thel'ower com partments through the apertures b, and thus relieves the shaft from the strain in the inverse 7 5 direction. 'As the drum is being rotated continuallyitwillcheck the movementcontinually; but at the same time the liquid continually flows back through the apertures a. If the said apertures are very small and the liquid can flow back but very slowly, the rotary movement of the shaft will be checked much more than if the apertures b were largeran d theliquid can flow back more rapidly. By varying the size of the drum and the size of the apertures the speed of a motor can be regulated at will.

Sand or other granulated or pulverized material can be used equally as well as liquids.

In the modification shown in Figs. 3 and 4, the drum is provided with a circular centerpiece, E, forming an annular space along the periphery of the drunnwhich space is divided into a series of compartments, a, by radial slats f, between which slots are formed. In this case the liquid or sand flows back through 5 the said slots; otherwise the device operates the same as before, and can be adjusted by varying the size of the drum and the size of the slots.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. Aregulator for motors, made substantially as herein shown and described, and consisting ofa closed drum divided into compartments by radial partitions provided with apertures or' slots, which drum is to contain a quantity of liquid or sand or other granular or pulverized material, as set forth.

2. In a regulator for motors, the combination, with the closed drum A, of the radia1- partitions E, provided with apertures b at or near the outer ends, substantially as herein shown and described, and for the purpose set forth.

3. In a regulator for motors, the combina 2o 7 OSKAR DITTMAR. CARL SCHMIDT.
